At an outdoor festival attracting tens of thousands, not every visitor can have a prime position in front of the main stage. Gimpo Laveniche Festival 2026, held in October, relayed the main performances from Hangang Central Park’s floating stage to LED screens in nearby viewing zones and throughout the Laveniche commercial district, showing a plan to disperse dense crowds at the stage and drive local sales.
From a professional event planner’s perspective, a Distributed Feed sending main-stage video to another area 1 km away does not end with installing a large monitor. It combines network architecture and route management: controlling major delays between video and sound while designing routes so audiences at relay points do not block the way.
1. Video and audio Latency: bring separated lips and sound together
Latency inevitably occurs as the stage’s picture and sound pass through wired or wireless networks to LED screens in the commercial district hundreds of metres away.
- Match video/audio Lip-sync: there is a time difference between sound travelling directly through the air from the main stage’s large speakers and the singer’s lip movements on the cable-fed LED screen. If the video provider and sound-rental supplier differ, the on-site Technical Director (TD) must stand at each relay spot and rehearse using the radio to enforce Tuning of the Delay Speaker’s audio timing to match the video.
- Signal-loss Failover: if relay video cuts out because a fibre cable breaks or wireless frequencies interfere, do not leave the commercial-district LED screen displaying No Signal. A backup Switcher system is essential, with an emergency festival Loop video or information captions connected to the relay Rack so the picture can switch within one second.
2. Audience routes and walkway occupancy: "The screen creates a new bottleneck"
The moment a screen is installed in a commercial area, it becomes a miniature audience space rather than a simple passage.
- Prevent shop entrances and passages being shut down: when choosing the screen position, obstruction by standing people matters more than the location of a power socket. If 50 people gathered in front block a nearby restaurant entrance or a passage at least 1.5 m wide for wheelchairs/pushchairs, the screen becomes a burden obstructing business rather than helping merchants’ sales.
- Physically tape the designated Viewing Zone: mark the floor in front of relay screens with tape or Tensa barriers so visitors can visually recognize the limit: “This is a passage from here onwards; do not stand here to watch.”
3. The blind spot in performance measurement: evidence that screens helped the commercial district
Quantitative supporting data is needed to report to municipalities or sponsors that relay equipment successfully dispersed the audience after the festival.
- Record Concurrent Viewers: do not collapse everything into total venue visits. At a peak such as the 20:00 fireworks show, simultaneously count the main-stage audience and people at relay spots A, B and C, quantifying a dispersal percentage.
- Establish a local-sales comparison: before treating nearby shops’ sales as an outcome of relay screens, establish a Control Group comparison with sales in the same period the previous year or in another block without a screen.
4. A four-stage Distributed Feed acceptance protocol for practitioners
When setting up relay spots, the lead on-site planning team and technical production team must follow these four-stage criteria.
| Stage | Actions |
|---|---|
| [Stage 1: Clarify transmission/reception R&R] | Specify in the contract the signal handover points and primary responsibility for failures between Provider A’s camera filming/switching, Provider B’s fibre/wireless transmission and Provider C’s destination LED/speaker rental. |
| [Stage 2: Simulate Sightlines and routes] | Before installing relay screens, draw the expected audience-concentration radius on the plan and cross-check for encroachment on shop entrances/exits and fire lanes. |
| [Stage 3: On-site Tech Run and Tuning] | On the day before the performance, under the same lighting and noise conditions as the main event, complete delay correction between the main-stage video feed and relay speakers. |
| [Stage 4: Activate the blackout emergency-evacuation manual] | Hand over a Script for safety staff in the area to announce by megaphone if the relay signal is permanently lost: “The performance will continue with audio only at this location” or “Please move slowly towards the main square.” |
A planner’s note: the moment the screen switches on, that place is a stage too
Even an LED screen on a shop wall 1 km away becomes a second stage for visitors the moment it shows the festival’s main video feed.
Planners must not mistake running a cable and switching on the picture for completing their task. Predict the crowd around the broadcast screen and perfectly provide space to stay, a route to leave and on-site staff to cool visitors’ anger if the sound suddenly stops. Only then is a Distributed Feed complete in the true sense.
Conditions for applying this elsewhere
When relaying performances to viewing areas or shopping streets away from the main stage.
